Embodiment 1

[0042] An active kitchen fire prevention and alarm device provided by a preferred embodiment of the present invention includes:

[0043] The infrared array sensor is used to monitor the temperature of the kitchen stove 2 in real time, and send the monitored temperature data to the processing storage module. In this embodiment, the model of the infrared array sensor is MLX90621.

[0044] The processing storage module is used to receive the monitored data and find out the maximum temperature value T in the temperature data received twice before and after max1 and T max2 , then based on the temperature value T max1 and T max2 Comprehensively calculate the difference between the different values, and judge whether to call the police according to the calculation results. If an alarm is required, the alarm signal is sent to the alarm module. The processing and storage module includes a processing chip and a flash storage module. In this embodiment, the model of the processing c...

Embodiment 2

[0049] On the basis of Embodiment 1, the preventive alarm device 1 further includes a human body identification module for detecting human body signals in the kitchen, and the human body identification module sends the detected human body identification signals to the processing and storage module. In this embodiment, the human body identification module uses a PIR pyroelectric infrared sensor. When the calculation result is abnormal, the processing chip performs corresponding processing according to the human body data detected by the PIR pyroelectric infrared sensor. If the PIR pyroelectric infrared sensor detects that there is no one in the kitchen or someone is in the kitchen but not in front of the stove, it will directly send an alarm through the warning module; if it detects that there is someone in the kitchen and is in front of the stove, it will not alarm.

Embodiment 3

[0051] On the basis of any of the above embodiments, the preventive alarm device 1 further includes an environment detection module for detecting the concentration of ambient gas in the kitchen, and the environment detection module sends the detected concentration data to the processing and storage module. In this embodiment, a CO sensor and a smoke sensor are selected for the environmental detection module. Obtain the concentration of gas in the kitchen environment through the CO sensor and smoke sensor, and send the detected concentration data to the processing chip. The processing chip performs comprehensive calculations based on the received data, and makes correct calculation output, avoiding the use of a single detection device. The resulting false alarms improve the accuracy of the device for preventing alarms.

Abstract

The invention discloses an active kitchen fire prevention alarm device, relating to the field of safety devices. The active kitchen fire prevention alarm device comprises an infrared array sensor, anenvironment detecting module, a human body identification module, a wireless communication module, a processing and storage module, a warning module and a power supply management module, wherein the infrared array sensor is used for monitoring temperature of a plurality of position points on a kitchen stove in real time; the environment detecting module is used for detecting ambient gas concentration in a kitchen; the human body identification module is used for detecting human body signals in the kitchen; the wireless communication module is used for connecting the active kitchen fire prevention alarm device with terminal equipment; the processing and storage module is used for receiving monitored data, and carries out comprehensive calculation based on a difference value of maximum temperature values in temperature difference data received twice sequentially, judging whether an alarm is needed according to a calculation result, and transmitting an alarm signal to the warning module if necessary; the warning module is used for receiving the alarm signal and giving out an alarm; and the power supply management module is used for providing electric energy to the modules. The activekitchen fire prevention alarm device can predict a fire in advance and notify the user to make corresponding treatment without being affected by the open fire normally used in the kitchen and the smoke generated by normal cooking.

Description

technical field [0001] The invention relates to the field of safety devices, in particular to an active kitchen fire prevention and alarm device. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the safety of home life. At present, the products used for kitchen fire safety monitoring mainly use smoke alarms, infrared or ultraviolet fire detectors and some fire detection equipment for image recognition through cameras. (normal oil fume produced during cooking), it is easy to cause false alarms of fire detection equipment. The above-mentioned fire detection devices are all passive detection devices, that is, only when a fire accident has occurred will an alarm operation be generated, and a certain degree of loss has actually been caused at this time. In addition, the use of fire detection equipment for image recognition through cameras not only has the disadvantages ...
